High current surge rating delivers a 100 kAIC interrupt capacity, allowing the SPD100240H1N to divert extreme transients away from critical drives and controllers. This reduces insulation stress, minimizes downtime, and extends motor life in high-energy startup environments. It’s ideal for manufacturing lines with variable loads and frequent motor starts. 240V delta (4W+G) operation provides compatibility with common industrial power configurations, reducing wiring complexity and enabling straightforward integration into mixed-load panels and high-leg delta systems. This supports quicker project timelines and safer energizing sequences. NEMA 4X enclosure offers weatherproof and corrosion-resistant protection, enabling outdoor installations and damp environments without compromising performance. This translates to fewer enclosure-related failures and lower maintenance costs for outdoor switchgear and washdown areas. External side mounting simplifies retrofit and accelerates installation by allowing installation adjacent to distribution equipment, reducing field labor and enabling rapid protection upgrades in crowded electrical rooms. Basic feature package delivers essential surge protection with straightforward commissioning and predictable upfront cost, making it suitable for new builds and standard panelboards seeking reliable protection with minimal complexity. A 15-year warranty paired with UL 1449 compliance provides long-term asset protection and peace of mind, supporting maintenance planning and improving total cost of ownership in critical production environments.
